Led by Mark Stoeckle, Daniel Kronauer and Christoph von Beeren with the aid of Hunter College High School student Joyce Xia, the National Cockroach Project has already learned a lot about the genetic diversity of New York City cockroaches, the Wall Street Journal reports. Cockroaches in the city do not have a lot of genetic diversity, according to the researchers, with 90 percent of cockroaches from Staten Island coming from the same gene pool, and with 80 percent reported for cockroaches from the Upper East Side of Manhattan, WSJ notes.
